The present invention is to provide an overlapped two-way clutch assembly for a rotary body driving apparatus which is safe, generates low noise, has great durability due to not using a lubricant at all, and is applicable regardless of various weights, and does not use a wrap spring. The overlapped two-way clutch assembly for a rotary body driving apparatus includes two-way driving clutch assemblies (710, 720, 730) rotatably coupled at a temporary driving member to transfer power of the driving member only in a forward direction; two-way driven clutch assemblies (740, 750, 760) transferring the power transferred from the two-way driving clutch assemblies only in the forward direction to output the power of the two-way driving clutch assemblies to the outside; and an insertion body selectively attached to or detached from the two-way driven clutch assemblies. When the power of the temporary driving member is transferred in the forward direction, the power transfer from the two-way driving clutch assemblies to the two-way driven clutch assemblies is selectively carried out. When inadvertent power is applied in the direction opposite from the forward direction, the power transfer inside the two-way driven clutch assemblies is locked in the insertion body and a brake is operated and the two-way driving clutch assemblies are in a release state. |
